Fault is not stored into fault history. F 71 Brake Control Fault Load information from hoist control unit is out of operation window F 73 Both Dir Active Both direction signals are active at same time >500ms A = Can be done by the user B = Can be done only by manufacturer authorized personnel Reset: switch power off and restart after the lamps of display are off. Check: SSU status (System menu / System info / Expander boards / C: SSU / status) SSU LED’s If the fault comes again, contact service Check: set SSU overspeed limit under 140% of maximum frequency motor type plate parameters maximum frequency parameters Check other hoisting inverter: fault history brake operation Check Ain2 wiring settings of load measuring device Check controller operation wiring of direction signals X X X X X 10.3.1 Fault time data record When a fault occurs, the fault number is displayed. By pushing the menu button right here you will enter the Fault time data record menu, indicated by T.1-T.13. In this menu, some selected important data valid at the time of the fault are recorded. The data available are: T.1 Counted operation days d T.2 Counted operation hours hh:mm:ss T.3 Output frequency Hz T.4 Motor current A T.5 Motor voltage V T.6 Motor power % T.7 Motor torque % T.8 DC voltage V T.9 Unit temperature °C T.10 Ready Run 0=Not Ready 0=Not Running T.11 Direction 0=Off 1=On Fault 0=No 1=Yes T.12 Warning 0=No 1=Yes At reference 0=No 1=Yes T.13 0-speed 0=Not Zero Speed 1=Zero Speed 1=Ready 1=Run 54/79 This document and the information contained herein, is the exclusive property of R&M Materials Handling Inc. and represents a non-public, confidential and proprietary trade secret that may not be reproduced, disclosed to third parties, altered or otherwise employed in any manner whatsoever without the express written consent of R&M Materials Handling Inc.

10.3.2 Fault Counter R&M Materials Handling, Inc. 4501 Gateway Boulevard Springfield, Ohio 45502 P.: (937) 328-5100 FAX: (937) 325-5319 V4.5.1 Fault Counter Fault counter value. Counter value is shown in format Fault counter value. Fault number. E.g. 12.01 means that there has been 12 pieces overcurrent faults. xx.01 xx.02 xx.03 xx.07 xx.09 xx.10 xx.11 xx.12 xx.13 xx.14 xx.25 xx.41 xx.53 xx.56 xx.57 xx.61 xx.62 xx.63 xx.99 When counter value is blinking, then you can monitor fault counter values by pressing up and down arrows. Overcurrent fault counter Overvoltage fault counter Earth fault counter Saturation trip fault counter Undervoltage fault counter Input line supervision fault counter Output phase supervision fault counter Braking chopper supervision fault counter Inverter undertemperature fault counter Inverter overtemperature fault counter Microprocessor watchdog-fault counter IGBT temperature fault counter Profibus communication error fault counter Generator side current limit fault counter Thermistor fault counter Overspeed fault counter Speed difference fault counter Stall supervision fault counter Sum counter of following faults: F4, F5, F8, F22, F23, F24, F26, F32, F33, F34, F35, F36, F37, F38, F39, F40, F48, F50, F54, F55, F60, F64, F65, F71, F72 V4.5.2 Total Faults Total number of all faults. 10.4 Inverter Alarm codes Alarm is a sign of an unusual operating condition. Alarm remains in the display for about 30 seconds. Alarm code Possible cause Checking A 16 Motor overtemperature A 50 Reference value alarm A 80 Multistep sequence alarm Mathematical motor temperature model has detected motor overheating. Motor is overloaded. Analog input signal is out of selected range 1- 9V or 2-10V control cable is broken signal source has failed Controller does not operate accurately Check: motor load if no overload exists, then check motor temperature model parameters Check: reference cable reference source Check: controller A 82 Overweight alarm A 83 Slack cable alarm Motor load is over adjusted value Motor load is under adjusted value Check: Overweight limit value Check: Slack cable limit value 55/79 This document and the information contained herein, is the exclusive property of R&M Materials Handling Inc. and represents a non-public, confidential and proprietary trade secret that may not be reproduced, disclosed to third parties, altered or otherwise employed in any manner whatsoever without the express written consent of R&M Materials Handling Inc.
